SASH-FASTENER.

Speccation of Letters Patent.

Patented Nov. 2, 1909.

Application filed October 30, 1908. Serial No. 460,292.

To all whom it may concern.'

Be it known that I, CHARLES A. HUNT, States, residing at Newburgh, inthe county of Orange and State of New York, have invented new and usefulImprovements in Sash-Fasteners, of which the following is aspecilication.

This invention relates to sash fasteners and its object is to provide acompact and substantial device to be located in the window frame and beprovided with bolts to engage racks on the sashes to prevent themovement of same in one direction as will be more fully explained in thefollowing specification, set forth in the claim and illustrated in thedrawing, where:

Figure l is a cross sectional view through a sash frame and the sashesof a window. Figs. 2, 3 and Al are vertical sectional views on the lines2 2, 3 3 and 1 -4. Figs. 5 and 6 are detail views. Fig. 7 is a view of amodilied form of fastener.

This fastener is designed to be of few parts, substantial and strong andto be of such dimensions as to be fitted into a mortise made in anordinary window frame with the usual compartments 11 and 12 for the sashweights and a parting strip 13. The upper sash 14 and the lower sash 1.5have on their edge adjacent to the frame, the rack bai's 16 and 17respectively with teeth having flat or horizontal sides and a reversebeveled side.

The fastener consists of a box 18 ittin in a mortise in the wall of theframe, the depth of the box being identical with the thickness of thewall, and its outer side is a perforated plate 19 by which it may beattached to the frame. Within the box 1S are two outwardly pressed bolts2O and 21 whose outer ends are beveled to conform with the teeth oftheir respective rack bars 16 and 17 while two sides of the rear endhave a flange 22 projecting downward and towai'd each other. In the rearof the two bolts are recesses 23 in which are located cups 24 thatconline coiled springs 25 to force the bolts outward into engagementwith the rack bars, the forward ends of the bolts being reduced so thatthe shoulder 2G-permits only the beveled end to extend beyond the plate19.

A filling block 27 with lateral flanges 23 for the bolts to slide on isplaced in the lower front corner of the box and directly back of same isthe shaft 29 of the key carrying the bit 30 that occupies the spacebetween the anges 22 and the filling piece 27, the latter preventing theforward movement of the bit and has a broad flange 31 which prevents itsdislocation and side movement into the space beneath the bolts. One endof the shaft 29 is squared so that an extension 34 may be fitted on thekey to turn it and project beyond the side of the frame to bemanipulated.

In order to further simplify the construction of the fastener the twocups 24 may be dispensed with and a flat spring' 33, as shown in Fig. 7,take their rear ends of the bolts.

The two bolts are normally extended by the springs engaging the rackbars and preventing' the downward movement 0f the upper sash or theupward movement of the lower sash. By turning the key shaft, the rearmovement of the bit forces back the bolts and when the bit is in ahorizontal position the upper flat face being under pressure of theflanges of the bolts, remains in that position and prevents the returnof the bolts to the outer position and the sashes are free to move up ordown.

The beveled faces of the rack bars allow the sashes to be moved to theirclosed posi` tions.

The compact construction of this sash fastener does not interfere withthe operation of the sashes and particularly of the weights as has beenthe case with similar devices heretofore patented and in case it isdesired to discontinue the use of the device the key is turned and thebit allowed to remain in its horizontal position, retracting the bolts.The extension 32 is withdrawn and the appearance of the window frame isnot altered.

It is obvious that the parts may be otherwise arranged or modifiedwithout departing from the essential features shown.

What I claim as new and desire to secure by Letters Patent is:

In a sash fastener, the combination with a box adapted to fit in thewall of the window place and bear upon the' the bolts, cups fitting inthe rear end of the the flanges, and a filling piece preventing theforward movement of the key.

In testimony whereof I aiiix my signature in presence of two Witnesses.
